Background technology
Navigation mark is the abbreviation of aids to navigation, and index shows the mark of direction along ng a path, boundary and obstruction, including crossing mark, edge
Shore beacon, beacon, transit leading mark, head and stern leading marks, lateral marks, separate channel mark, position indicating mark, flood mark and bridge mark etc..It is to aid in
Guide the artificial target of ship's navigation, positioning and sign obstruction with representing warning.
Navigation mark is made up of heavy stone, anchor chain, floating drum, lamp bracket, and cat face is connected to heavy stone and floating drum.Heavy stone uses prefabricated water mostly
Clod（Also there is cast iron casting）, bottom indents, 3 ~ 12 tons are typically weighed about, is sunken in the mud in river course, so not easily shifted, it is ensured that on
The floating drum in face will not drift（Unless anchor chain is broken）.
Existing heavy stone uses the pre-cast concrete block of some simple structures mostly, using process it occur frequently that navigation mark has upwards
The phenomenon of skew, because navigation mark position is offset, it can become twisted often over a period of time later original straight navigation mark line
Turn round.
The reason for these navigation marks are offset is that this skew has a spy because heavy stone shifts in the presence of current
Point, exactly heavy stone can sail against the current.This right two parts reason of phenomenon causes：
（1）Referring to accompanying drawing 1, according to bernoulli principle, i.e.,：Kinetic energy+gravitional force+pressure potential=constant.It is the most famous
Inference be：During contour flowing, flow velocity is big, and pressure is with regard to small.Current pass through stone 10 at a high speed in the front upper place of stone 10 in accompanying drawing 1
The flow velocity of current at anterior position 7 is much higher than the water velocity at the rear position 8 of stone 10, therefore at anterior position 7
Pressure is less than the pressure at rear position 8, and pressure differential causes stone 10 to be sailed against the current；
（2）Referring to accompanying drawing 1, stone 10 is pressed on the sediment deposit 9 in riverbed, and the silt in the front of stone 10 can be by the water of high speed
Stream is taken away, and the pit of a crescent, effect of the stone 10 in gravity and above-mentioned difference force can be formed in the front of stone 10
Under can turn forward, displacement forward occurs.
In the prior art in order to avoid heavy stone drift is moved, using the method for big weight stone, the big current difference of stone weight is led
The transportation of the pressure difference of cause is limited.
Utility model content
The purpose of this utility model is to provide a kind of Navigation Mark concrete prefabricated heavy stone, to solve above-mentioned background technology
In the problem of mentioning.
To achieve the above object, the utility model provides following technical scheme：A kind of concrete prefabricated heavy stone of Navigation Mark,
Including heavy stone body and conical points foot, anchor chain retainer ring, described anchor chain retainer ring is arranged on the top of heavy stone body, institute
The conical points stated are evenly distributed on heavy stone body bottom portion and the edge of bottom enough；Described heavy stone body and conical points foot
The overall structure being formed in one.
Behind the utility model input river course, its conical points can penetrate the silt layer in riverbed enough, the cone in insertion riverbed depths
Under the obstruction of shape point foot, pressure difference will not cause the utility model displacement caused by the current difference before and after the utility model.
Preferably, 25 °~45 ° are skimmed outside the setting angle of the conical points foot on bottom margin position.Therefore flowing water is in this reality
The position of the zap pit formed with new front will not it is cross-domain before the conical points skimmed press close to heavy stone body enough and cause gravity unbalance
Youngster tilts；Other fulcrum force of the present utility model is on conical points foot, even if heavy stone body nearby has the phenomenon of silt underwashing
Also its stress balance will not be destroyed；Moreover, heavy stone body nearby have silt underwashing fall after conical points can be pressurized enough sinking, more
Will not occurred level to displacement.
Preferably, the stone body upper surface that sinks also is provided with twice fluid ditch.Front and rear pressure difference of the prior art is because flow velocity
Difference causes, and because heavy stone body front end faces flowing water directly, flowing water is high in the flow velocity of front-end surface, because the stop of heavy stone body is made
With one side that heavy stone body facing away from flowing water can form a fluid dead band, and the speed of current is very slow, therefore front and rear current difference
It is larger.When the utility model is put into river course, make the direction of fluid ditch along the direction of current.Heavy stone body can so be reduced
The scope in the dead band of rear end, the flow velocity of heavy stone body rear end current is improved, reduce the current difference before and after heavy stone body, and then reduce
Front and rear pressure difference.
The advantages of the utility model, is as follows：
（1）It will not be subjected to displacement in bottom of river channel；
（2）Prior art is in order to avoid being subjected to displacement, using big heavy stone, heavy stone weight that the utility model uses
It is small, transport and lay and be more convenient.
Brief description of the drawings
Fig. 1 is the schematic diagram that stone countercurrently moves in river course in the prior art；
Fig. 2 is the utility model structure diagram；
Fig. 3 is the diagrammatic cross-section that the utility model sinks to river bed.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
